(II)
To further illustrate the specific implementation of the energy replenishment management system, taking an automobile charging station as an example, in this embodiment, the current distribution algorithm logic of the charging pile node is as follows:
wherein the node attribute information is shown in the following table:
when the power utilization state of the charging pile node changes (a new charging request is added and a charging ending event occurs), or the timed scheduling task is triggered within 30 minutes, the manager starts to distribute the power. The steps are as follows:
a. each node reports the status to the master manager 11 and first allocates the basic charging current.
b. The head manager 11 performs the first scheduling assignment: and polling all charging pile nodes by the general manager to acquire the information and management characteristics of the equipment of the replenishment object. And calculating the current distribution ratio of each node according to the customer level (namely the charging priority level) of each node, and issuing current distribution commands of all charging piles in a polling mode.
c. The manager performs second scheduling allocation: and the manager polls and issues the acquired charging pile equipment information. And recovering the redundant distributed power utilization current according to the actual power utilization current of the charging pile nodes, calculating a second round current distribution ratio according to the importance degree of each node, and sending the second round current distribution ratio to each charging pile substation in a polling manner.
d. The manager performs scheduling allocation for the third time: and polling and collecting the charging pile equipment information again by the manager, and recycling redundant power utilization current. And evenly distributing all charging pile nodes.
Calculation formula and allocation details such as setting parameters: the vehicle battery state CB is provided with a charge amount SB, a charge time ST, a remaining charge time RT, a customer level VIP, a total pile group distribution current TC (power is current voltage, and a uniform ac voltage 220V), a charge emergency degree UP is set as a charge time ST ÷ remaining charge time RT, a charge importance degree IP is set as (a charge amount SB — vehicle battery state CB) × customer level VIP, an emergency coefficient Ru, and an importance coefficient Ri.
Wherein the first charging schedule allocation:
the charging ratio M1 of the branch node is equal to the charging emergency degree UP multiplied by the emergency coefficient Ru;
the total charging ratio Mt of the pile group is M1+ M3+ M6+ … …;
the node distribution current A1 is equal to the total distribution current TC of the pile group multiplied by the node charging ratio M1 divided by the total charging ratio Mt of the pile group;
and (3) second-time charging scheduling distribution:
after the current is distributed to each sub-node for the first time, the master manager can perform sub-node polling operation for one time and acquire attribute information of each sub-node. And the master manager recovers the electric quantity of each node according to the electricity utilization current condition of each subnode and the current distributed by the subnodes. The recovery current RY-I1 is the branch node distribution current a1 — the actual consumer current I1.
If the value of the branch node recovery current RY-I1 is larger than 1A, the charging load is considered to be saturated. The secondary charging schedule allocation is not performed for this sub-node.
The node split current a1 is reset to the actual current: the node distribution current a1 is the actual power utilization current I1;
the total current RY-It is RY-11+ RY-I2+ … …;
the secondary current distribution ratio L1 is equal to the charge importance degree IP × importance coefficient Ri;
the total charging proportion Lt of the secondary pile group is LI + L3+ L6+ … …;
the secondary node redistribution current R1 is the recovery total current RY-It × the node secondary current distribution ratio L1 ÷ the pile group total charge ratio Lt.
And third charging scheduling allocation:
similarly, after the current is distributed for the second time, the master manager performs node polling operation again to acquire the attribute information of each sub-node. And the master manager recovers the electric quantity of each branch node according to the electric current utilization condition of each branch node and the current distributed by the branch node.
The recovery current RI-I1 is the branch node distribution current a 1-the actual consumer current I1.
If the value of the branch node recovery current RY-I1 is larger than 1A, the charging load is considered to be saturated, and the third charging scheduling distribution cannot be carried out on the branch node.
The total current RY-It is RY-I1+ RY-12+ … …;
the general manager redistributes the current of all the charging load unsaturated nodes, and the distribution principle is as follows: and (4) evenly distributing.
